Application filed July 12, 1915. Serial No. 39,316.

To all whom it may concern Be it known that I, PETER J. DE Does, a citizen of Holland, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Sofa-Bed; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to sofa beds, and particularly to those of the multiple section folding bed frame type.

' The object of my invention is the provision of an improved bed of the character described, which is simple and eflicient in its construction, capable of being easily folded, and unfolded and provided with improved means which is operable by folding and unfolding movements of the bed frame to automatically control the movements of the section locking means and to lock such means in section locking position when the bed frame is in predetermined position of its folding movements.

Further objects and advantages of the invention will be apparent from the following detailed description thereof.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a sectional view of a davenport frame with the bed-frame carried by the overturning seat thereof and in complete unfolded position, different stages of the folding of the bed-frame being indicated in dotted lines. Fig. 2 is a plan View of a side portion of the davenport seat and bed-frame in unfolded position shown in Fig. 1. Fig. 3 is a longitudinal section of the bed-frame in unfolded position and with parts broken away. Fig. 4 is a view of the bed frame and its carrying seat with the seat in section and with the bed-frame partly folded. Fig. 5 is a view similar to Fig. l with the bedframe compactly folded within the seat-frame, and with the seatframe in its overturned position. Fig. 6 is a front elevation of a portion of the davenport frame with the seatframe overturned and with the bed frame in unfolded position and in transverse section in advance of the seat frame, and. Fig. 7 is a fragmentary view of the bed frame and thesupporting parts partly folded in the seat frame.

Referring to the drawings, 1 designates a davenport frame, and 2 the seat-frame thereof, which is of hollow construction and pivoted at its ends to the ends of the davenport frame for overturning movements therein, as is well understood in the art. It will be understood that the seat 2 is mounted in any suitable'manner for overturning movements within the davenport frame. As such pivoting means for the seat forms no part of the present invention and is well understood in the art it is not shown in the drawings.

3 designates the top upholstered portion of the seat-frame when the seat-frame is in usable position as such.

The bed-frame, which is carried by the seat frame for folding movements therein, comprises, in the present instance, the three major sections 4, 5 and 6, and the minor sections 7 and 8, which connect the major sections 4, 5 and 5, 6, respectively. The several sections of the bed-frame are pivoted together in successive order, as shown in the drawings, and as well understood inthe art, the construction of the bed frame in this respect being similar to the bed frame in Patent No. 933,691 issued May 30, 1911, to A. C. Klopping, except that both of the minor sections 7 and 8 are of similar singlepiece construction instead of the section 7 being of the double-piece construction, as shown in said patent. Each minor section 7 and 8 has its sides connected and braced apart by a transverse brace-bar 9, which is pivoted at its ends to the respective sides of the section. The bar 9 is bowed downwardly intermediate its ends to prevent any interference with a downward. springing of the customary spring fabric (not shown) which is attached to the frame sections and forms a bed bottom. The bed section 8 is somewhat shorter than the bed section 7 so as to space the sections 4 and 5 a suflicient distance apart when in folded position to permit an interposing of the sections 6 and 8 therebetween, as shown in Fig. 5.

The inner bed frame section 4 is supported within the seat-frame 2 by a folding link construction, -which will now be described. A pair of toggle links 10, 10, which are pivoted together at their inner ends, as at 11, have their outer ends pivoted, one to the adjacent end of the seat-frame at the inner side thereof, as at 12, and the other to the inner end portion of the respective side of the bed-frame section 4, as at 13, said links forming supports for the inner end portion of the bed-frame section 4 when the seatframe is in inverted position and the bed frame is unfolded, as shown in Figs, 1, 2 and 4. A link 14 is pivoted at one end, as at 15, to the link 10, which is pivoted to the section 4, and has its other end pivoted to an upright link 16, as at 17. The link 16 is pivoted to the seat-frame end adjacent to the lower portion of the edge thereof, which is disposed forward when the seat is in inverted position, as at 18, and extends upward in vertical position from said pivot when the bed frame is in its unfolded position, as shown in Figs. 1 and 4. The upper end of the upright link 16 terminates in substantially the horizontal plane of the section 4 adjacent to its pivoted edge and is pivoted, as at 19, to a forwardly or outwardly extending link 20, which pivots at its outer or forward end, as at 21, to the bed-frame section 5 adjacent to its inner edge. A link 22 is pivoted at one end to the link 14, as at 23, and at its other end to the inner bed-frame section 4 adjacent to the forward or outer edge thereof, as at 24. A

control link 25 is also pivoted at 24 to the bed-frame section 4 and extends inward or rearward therefrom and pivots at its rear end to the adjacent end of the seat frame 2 near the inner upper edge thereof when in inverted position, as at 26. With this construction of links and manner described of connecting the same with the seat frame and bed frame sections, the toggle links 10, 10 when in straight position, serve to support the inner end of the bed-frame section 4, and the link 22 in conjunction with the link 14, which is in turn supported by the toggle links'lO and by the upright link 16, serve to support the forward or outer end portion of the bed frame section 4. Upon a raising or folding movement of the bed-frame section 5 relative to the sections 4 and 7 to the upright position indicated at D by dotted lines in Fig. 1, the link 20, which connects the section 5 with the upper end of the uprightlink 16, will impart a limited rearward or inward swinging movement to said link 16 and a consequent rearward breaking of the toggle links 10 due to the connection 14' between said links 16 and 10. A continued folding of the bed-frame section 5 over the section 4 from the dotted line position I) Will cause a collapsin of the toggle links 10 so as to lower the lnner end of the bed frame section 4 to its folded or collapsed position within the seatframe, in which position the inner end of the frame rests upon a supporting ledge 27 on the adjacent side of the seat-frame. The rearward movement of the link 14 during such collapsing movements of the toggle links 10 causes a rearward pulling of the lower end of the link 22 and a consequent collapsing or lowering of the forward or outer end portion of the bed frame section 4, such lowering being in unison with the lowering of the rear end of said section and guided by the link 25, which is pivoted at its rear or inner end to the seat frame, as at 26, and its forward or outer end to the section 4. I

It will be apparent that an unfolding of the bed section 5 from over the section 4 will cause a reverse action to that above described to take place, or in other words will move the bed frame supporting and control links to effect a raising of the inner bed frame section 4 to its operative position. It will of course be understood that like link constructions are provided at each side of the bed frame so as to cause each side of the section 4 to be supported and to have raising and lowering movements within the seat frame when the section 5 has folding or unfolding movements relative to the section 4..

Legs 28 and 29 support the bed frame sections 5 and 6 at the outer or forward edges thereof at each side of the bed frame, the leg 28 having its pivot in common with the pivot 30, which connects the sections 5 and 8.

A link 31 is disposed at the inner side of each side bar of the bed-frame section 5 lengthwise thereof, and has its rear end pivoted to the forward end of the respective side bar of the section 7, as at 32, said pivot being disposed in eccentric relation to the pivot 33, which connects the adjacent ends of the respective side bars of the bed-frame sections 5 and 7. The forward end of the link 31 carries a pin 34,, which projects laterally therefrom through a diagonally disposed longitudinally extending slot 35 in the respective side bar of the bed frame section 5 and attaches at its outer end to a link 36, which in turn is pivoted at its forward end to the adjacent leg 28 below its pivot 30, as at 37. Upon a folding movement of the bed-frame section 5 to the upright position D relative to the section 7 the links 31 at each side of the section 5 will have longitudinal movements relative to the section 5 sufficient to impart complete folding movements to the legs 28 through the connecting links 36. Said relative moveoccasioned by the pivoting of said links to the forward ends of the side bars of the section 7 in the offset relation to the pivots 33 indicated in'the drawings. It is evident that the connection between the section7 and the legs 28 thrbugh the medium of the links 31 and 36 will cause an automatic unfolding movement of said legs relative to the section 5 when said section is unfolded relativ to the section 7.

The legs 29, which support the outer end section 6 of the bed frame are controlled by a similar means to that employed for controlling the folding and unfolding movements of the legs 28. This outer leg controlling means comprises links 38 and 39 for each leg, the link 38 being disposed at the inner side of the respective side bar of the bed frame section 6 and has its rear end pivoted to the forward end of the respective side bars of'the section 8 in advance of the section connecting pivot 40, as shown at 41. The forward end of the link 38 is connected to the rear end of the link 39 by a pin 42, which projects through a longitudinally disposed slot 43 in the respective side bar of the section 6. The forward end of the link 39 is pivoted to the respective leg 29 slightly below its pivot. A sufficient longitudinal movement is imparted to the links 38 and 39 relative to the bed-frame section 6 upon folding and unfolding movements of said section relative to the section 8 to cause respective folding and unfolding movements of the attached leg 29 relative to the section 6.

The bed-frame section 6 is provided at its outer end with a foot-piece 44, the legs 45 I of which are preferably obtusely angled, and each is pivoted to the respective side of the section 6 slightly to the rear of its forward end, as at 46, (Fig. 4). The obtuse formation of the leg portions of the foot-piece 44 enable them, when in set-up or operative position, to extend forward to the upper forward edge of the section 6 and then upward on a slight forward incline, as shown in Fig. 1. A catch finger 47 is pivoted to each side of the section 6 slightly to the rear of the foot-piece pivot 46, as at 48, and is provided with a longitudinally extending slot 49 through which projects a pin 50 that is carried by and projects from the adjacent leg 45 of the foot-piece, in the present instance, at the point..of angle thereof. When the foot-piece is in the set-up or usable position shown in Fig. 1, the catch fingers 47 are held in forwardly reclining position by the pins 50, and a rearward swinging of the foot-piece to its folded position relative to the section 6 swings the catch fingers 47 to upright position with respect to said section or in substantially right angled relation to said section, as shown by the dotted line position A in Fig. 1, and by full lines in Fig. 4. The outer end of each catch finger 47 is slightly hooked at one edge thereof and has its opposite edge extended inthe form of a nose 51 having a ta ered or inclined inner edge. When the oot-piece 44 is in folded relation to the section 6 and said section is disposed in its folded position over the section 5, as indicated by the dotted line position C in Fig. 2, and in full lines in Fig. 4, the catch fingers 47 are disposed in position for their hooked end portions to engage the forward sides of pins 52, which fixedly project from the outer sides of the section 5. A pin 53 projects outwardly from each link 31 through a registering slot 54 in the respective side bar of the bedframe section 5, and is in proper position to adapt it to ride up over the incliged inner edge portion of the catch-finger 51 when said link 31 is moved relative to the section 5 upon a folding of said section relative to the section 7. The slot 54 is inclined relative to the longitudinal plane of the section 5 to guide the movement of the pin 53 over the inclined edge of the catch finger nose. When the bed frame section 5 is in its unfolded position as shown in Figs. 1, 2 and 4, the pin 53 is sufliciently spaced from the catch pin 52 to permit the free passage of the nose portion 51 of the catch-finger therebetween.

Upon an inward movement of the link 31 relative to the bed-frame section 5, the pin 53 rides up over the nose portion of the catch finger toward the pin 52 and serves to effectually retain the catch finger in locked engagement with the catch pin.

At each end of the seat frame adjacent to the upper forward edge thereof when disposed in inverted position, as shown in the drawings, is fixed an inwardly projecting hooked finger 56, and carried by each side of the bed frame section 4 adjacent to its tforward end is an outwardly projecting hooked finger 57 which has hooked engagement with the finger 56 when the bed frame section 4 is in its elevated usable position, as best shown in Fig. 6. The interlocking of the set of fingers 56 and 57 at each side of the bed frame serves to firmly brace the bed frame against transverse movements relative to the seat frame, and are found to be important in a bed of the character described.

It is apparent from the foregoing description that in folding the bed-frame from the unfolded or usable position thereof shown in Fig. 1, the foot-piece 44 is first swung rearward over the outer end section 6 to the dotted line position A, which movement of the foot-piece swings the catch-fingers 47, one of which is disposed at each side of the bed frame, the right angled position with respect to the section 6, as shown by said position A. The section 6 is next swung upward on its pivot 40 to the upright position B (Fig. 2), thus causing a forward movement of the links 38 and 39 relative to the section 6 and a consequent folding of the forward legs 29 against the under side of said section. The sections 6 and 8 are then swung over the section 5 on the pivot 30, such movement positioning the nose of each catch finger 47 in position to have catch engagement with the respective catch pin 52. The sections 5, 6 and are then swung up to the position D in Flg. l and then in reclining position over the inner section 4. The upward swinging of the section 5 to the position D imparts movements to the links 31 relative to said section and moves the lock-pins 53 into locking engagement with the nose portion of the catch fingers 47 and also swings the legs 28 into folded position against the under side of the section. The swinging of the section 5 over the section 4 also imparts a collapsing movement of the links 10, 14:, 16 and 22 and a consequent downward drawing of the bed frame within the seat-frame 2, as indicated in Fig. 5, the link 25 serving to control such lowering movements.
